Abstract: A data processing and communications system for communications between remote stations, the apparatus comprising; a communications module; and a data processing module, a power supply including a power source for generating power and a power link to said modules; a data and power link between the communications module and the data processing module to enable communications and mutual operations therebetween. A camera and MCU for each data transmission station is provided along with a frame comparator in the MCU to select characteristic frame image changes in an image transmission and means for ascertaining characteristic data/image changes based on comparison between each of a predetermined number of per second and next camera captures.

Abstract: A collision warning and avoidance system which comprising an integrated on-board Train Navigation Unit (3) and a GPS Interface Subsystem to locate a train. The system includes a GPS (2) location signal, at least one fixed transponder station (31) and a calibrated, rectified transponder identification subsystem for scanning the track based transponders for override of train controls in the event of a collision risk and further comprising a database of all transponders, their location and the track ID on which they are located. Data and information are computer processed and analysed in neural networks in one train to identify, rank, and evaluate collision hazards.
